Scheduling of Control Signaling on a Primary Cell by a Secondary Cell

ABSTRACT

A base station of a network configures a first search space having a first search space identification (SearchSpaceId) in a special cell (SpCell) and a second search space having a second search space identification (SearchSpaceId) in a secondary cell (SCell) for monitoring control signaling that schedules operations on the SpCell. The base station transmits a radio resource control (RRC) configuration to a user equipment (UE) including the first SSID and the second SSID, wherein the RRC configuration configures the UE to monitor the first search space having the first SSID for scheduling of a first type of control signaling and the second search space having the second SSID for scheduling of a second type of control signaling.

BACKGROUND

When establishing the network connection such as, for example, aconnection to a 5G new radio (NR) network, a next generation NodeB (gNB)transmits downlink channel information (DCI) to the UE via a physicaldownlink control channel (PDCCH). The PDCCH is transmitted to the UE viaone or more control resource sets (CORESETS). Because 5G new radio (NR)spectrum is difficult to obtain and expensive, operators have utilizeddynamic spectrum sharing (DSS) so that 5G NR and long term evolution(LTE) transmissions can coexist in the same spectrum. However,transmissions of the CORESETS for 5G communications may interfere withcell reference signals (CRS) transmissions on the LTE network.

The exemplary embodiments may be further understood with reference tothe following description and the related appended drawings, whereinlike elements are provided with the same reference numerals. Theexemplary embodiments relate to the configuration of search spaces whena secondary cell (SCell) is configured to schedule UE operations on aspecial cell (SpCell) in addition to the SpCell also being configured toschedule its own operations. In the following description, SpCell mayrefer to a primary cell (PCell) or a primary SCell (PSCell).

The exemplary embodiments are described with regard to a UE. However,reference to a UE is merely provided for illustrative purposes. Theexemplary embodiments may be utilized with any electronic component thatmay establish a connection to a network and is configured with thehardware, software, and/or firmware to exchange information and datawith the network. Therefore, the UE as described herein is used torepresent any appropriate electronic component.

In addition, the exemplary embodiments are described with regard to a 5GNew Radio (NR) network. However, reference to a 5G NR network is merelyprovided for illustrative purposes. The exemplary embodiments may beutilized with any network that implements the functionalities describedherein.

To provide more flexibility to a 5G NR network using dynamic spectrumsharing (DSS) to schedule control data to be transmitted, it has beensuggested that in addition to configuring a SpCell (e.g., a 5G cell) toschedule its own transmissions, a SCell (e.g., a 5G cell) also beconfigured schedule operations on the SpCell. One issue that arises,however, is how the search space(s) (SS) should be configured tofacilitate the scheduling of these transmissions on the SpCell by twocells (the SpCell and the SCell).

According to some exemplary embodiments, the network configures one ormore search spaces in at least one of the SpCell and the SCell forscheduling the control data transmissions on the SpCell. The networkindicates to the UE which search space(s) should be monitored for thisscheduling.

Another issue that arises is how a UE should handle the deactivation ordormancy of an SCell when the scheduling of control data transmissionson the SpCell is performed by both the SpCell and the SCell.

According to other exemplary embodiments, the network configures the oneor more search spaces for each of the SpCell and the SCell. The networkthen explicitly or implicitly indicates to the UE which search space theUE should monitor when the SCell is deactivated or dormant.

FIG. 1 shows an exemplary network arrangement 100 according to variousexemplary embodiments. The exemplary network arrangement 100 includes aUE 110. It should be noted that any number of UE may be used in thenetwork arrangement 100. Those skilled in the art will understand thatthe UE 110 may be any type of electronic component that is configured tocommunicate via a network, e.g., mobile phones, tablet computers,desktop computers, smartphones, phablets, embedded devices, wearables,Internet of Things (IoT) devices, etc. It should also be understood thatan actual network arrangement may include any number of UEs being usedby any number of users. Thus, the example of a single UE 110 is merelyprovided for illustrative purposes.

The UE 110 may be configured to communicate with one or more networks.In the example of the network configuration 100, the networks with whichthe UE 110 may wirelessly communicate are a 5G New Radio (NR) radioaccess network (5G NR-RAN) 120, an LTE radio access network (LTE-RAN)122 and a wireless local access network (WLAN) 124. However, it shouldbe understood that the UE 110 may also communicate with other types ofnetworks and the UE 110 may also communicate with networks over a wiredconnection. Therefore, the UE 110 may include a 5G NR chipset tocommunicate with the 5G NR-RAN 120, an LTE chipset to communicate withthe LTE-RAN 122 and an ISM chipset to communicate with the WLAN 124.

The 5G NR-RAN 120 and the LTE-RAN 122 may be portions of cellularnetworks that may be deployed by cellular providers (e.g., Verizon,AT&T, T-Mobile, etc.). These networks 120, 122 may include, for example,cells or base stations (Node Bs, eNodeBs, HeNBs, eNBS, gNBs, gNodeBs,macrocells, microcells, small cells, femtocells, etc.) that areconfigured to send and receive traffic from UE that are equipped withthe appropriate cellular chip set. The WLAN 124 may include any type ofwireless local area network (WiFi, Hot Spot, IEEE 802.11x networks,etc.).

The UE 110 may connect to the 5G NR-RAN 120 via the gNB 120A and/or thegNB 120B. The gNBs 120A and 120B may be configured with the necessaryhardware (e.g., antenna array), software and/or firmware to performmassive multiple in multiple out (MIMO) functionality. Massive MIMO mayrefer to a base station that is configured to generate a plurality ofbeams for a plurality of UE. During operation, the UE 110 may be withinrange of a plurality of gNBs. Reference to two gNBs 120A, 120B is merelyfor illustrative purposes. The exemplary embodiments may apply to anyappropriate number of gNBs. Further, the UE 110 may communicate with theeNB 122A of the LTE-RAN 122 to transmit and receive control informationused for downlink and/or uplink synchronization with respect to the 5GNR-RAN 120 connection.

Those skilled in the art will understand that any association proceduremay be performed for the UE 110 to connect to the 5G NR-RAN 120. Forexample, as discussed above, the 5G NR-RAN 120 may be associated with aparticular cellular provider where the UE 110 and/or the user thereofhas a contract and credential information (e.g., stored on a SIM card).Upon detecting the presence of the 5G NR-RAN 120, the UE 110 maytransmit the corresponding credential information to associate with the5G NR-RAN 120. More specifically, the UE 110 may associate with aspecific base station (e.g., the gNB 120A of the 5G NR-RAN 120).

In addition to the networks 120, 122 and 124 the network arrangement 100also includes a cellular core network 130, the Internet 140, an IPMultimedia Subsystem (IMS) 150, and a network services backbone 160. Thecellular core network 130 may be considered to be the interconnected setof components that manages the operation and traffic of the cellularnetwork. The cellular core network 130 also manages the traffic thatflows between the cellular network and the Internet 140. The IMS 150 maybe generally described as an architecture for delivering multimediaservices to the UE 110 using the IP protocol. The IMS 150 maycommunicate with the cellular core network 130 and the Internet 140 toprovide the multimedia services to the UE 110. The network servicesbackbone 160 is in communication either directly or indirectly with theInternet 140 and the cellular core network 130. The network servicesbackbone 160 may be generally described as a set of components (e.g.,servers, network storage arrangements, etc.) that implement a suite ofservices that may be used to extend the functionalities of the UE 110 incommunication with the various networks.

FIG. 2 shows an exemplary UE 110 according to various exemplaryembodiments. The UE 110 will be described with regard to the networkarrangement 100 of FIG. 1 . The UE 110 may represent any electronicdevice and may include a processor 205, a memory arrangement 210, adisplay device 215, an input/output (I/O) device 220, a transceiver 225and other components 230. The other components 230 may include, forexample, an audio input device, an audio output device, a battery thatprovides a limited power supply, a data acquisition device, ports toelectrically connect the UE 110 to other electronic devices, one or moreantenna panels, etc. For example, the UE 110 may be coupled to anindustrial device via one or more ports.

The processor 205 may be configured to execute a plurality of engines ofthe UE 110. For example, the engines may include a search spacemanagement engine 235. The search space management engine 235 mayperform various operations related to determining which search space(s)should be monitored for control data scheduling for the SpCell, as willbe described in greater detail below.

The above referenced engine being an application (e.g., a program)executed by the processor 205 is only exemplary. The functionalityassociated with the engine may also be represented as a separateincorporated component of the UE 110 or may be a modular componentcoupled to the UE 110, e.g., an integrated circuit with or withoutfirmware. For example, the integrated circuit may include inputcircuitry to receive signals and processing circuitry to process thesignals and other information. The engines may also be embodied as oneapplication or separate applications. In addition, in some UE, thefunctionality described for the processor 205 is split among two or moreprocessors such as a baseband processor and an applications processor.The exemplary embodiments may be implemented in any of these or otherconfigurations of a UE.

The memory arrangement 210 may be a hardware component configured tostore data related to operations performed by the UE 110.

Thetransceiver 225 may be a hardware component configured to establish aconnection with the 5G NR-RAN 120, the LTE-RAN 122, the WLAN 124, etc.Accordingly, the transceiver 225 may operate on a variety of differentfrequencies or channels (e.g., set of consecutive frequencies).

FIG. 3 shows an exemplary network base station, in this case gNB 120A,according to various exemplary embodiments. The gNB 120A may representany access node of the 5G NR network through which the UE 110 mayestablish a connection. The gNB 120A illustrated in FIG. 3 may alsorepresent the gNB 120B.

The gNB 120A may include a processor 305, a memory arrangement 310, aninput/output (I/O) device 320, a transceiver 325, and other components330. The other components 330 may include, for example, a power supply,a data acquisition device, ports to electrically connect the gNB 120A toother electronic devices, etc.

The processor 305 may be configured to execute a plurality of engines ofthe gNB 120A. For example, the engines may include a search spacemanagement engine 335 for performing operations including configuringone or more search spaces when both the SpCell and the SCell areconfigured to schedule control data transmissions on the SpCell and toconfigure the UE 110 to handle the deactivation or dormancy of theSCell. Examples of this process will be described in greater detailbelow.

The above noted engine being an application (e.g., a program) executedby the processor 305 is only exemplary. The functionality associatedwith the engines may also be represented as a separate incorporatedcomponent of the gNB 120A or may be a modular component coupled to thegNB 120A, e.g., an integrated circuit with or without firmware. Forexample, the integrated circuit may include input circuitry to receivesignals and processing circuitry to process the signals and otherinformation. In addition, in some gNBs, the functionality described forthe processor 305 is split among a plurality of processors (e.g., abaseband processor, an applications processor, etc.). The exemplaryaspects may be implemented in any of these or other configurations of agNB.

The memory 310 may be a hardware component configured to store datarelated to operations performed by the UEs 110, 112.

Thetransceiver 325 may operate on a variety of different frequencies orchannels (e.g., set of consecutive frequencies). Therefore, thetransceiver 325 may include one or more components (e.g., radios) toenable the data exchange with the various networks and UEs.

FIG. 4 shows a method 400 of configuring a search space of a SCell(e.g., a 5G cell) for scheduling transmissions on a SpCell (e.g., a 5Gcell) according to various exemplary embodiments. At 405, the gNB 120A(or 120B) configures an SpCell (e.g., gNB 120A) and an SCell (e.g., eNB122A) to schedule control data transmissions (e.g., DCI, PDCCH, etc.)for the SpCell. In some embodiments, the SCell cannot be configured infrequency range 2 (FR2). In some embodiments, whether or not the SCellcan be configured in FR2 depends on the capabilities of the UE. In someembodiments, the SCell cannot be configured in the non-terrestrialnetwork (NTN) spectrum. In some embodiments, the SCell cannot beconfigured in the NR unlicensed (NR-U) spectrum. In some embodiments,whether or not the SCell can be configured in the NR-U spectrum dependson the capabilities of the UE.

At 410, the gNB 120A configures a first search space in the SpCell and asecond search space in the SCell. In some embodiments, the first andsecond search spaces have the same search space ID (SearchSpaceId). Insuch an embodiment, the two search spaces are automatically linkedbecause when the gNB 120A configures the UE 110 with the SearchSpaceIdto monitor, then that SearchSpaceId corresponds to the first and secondsearch spaces. In some embodiments, when the first and secondSearchSpaceIds are the same, the nrofCandidates information element (IE)is in the first search space of the SpCell and all other control signalconfigurations (e.g., non-fallback DCI, remaining PDCCH configurations)are in the second search space of the SCell. In some embodiments, whenthe first and second SearchSpaceIds are the same, the nrofCandidates IEand some other control signal configuration (e.g.,monitoringSlotPeriodicityAndOffset, monitoringSymbolsWithinSlot,duration) is in the first search space of the SpCell and all othercontrol signal configurations (e.g., non-fallback DCI, remaining PDCCHconfigurations) are in the second search space of the SCell.

In some embodiments, the first and second search spaces and theircorresponding SearchSpaceIds are different. In such an embodiment, thefirst search space of the SpCell includes fallback DCI scheduling (e.g.,Format 0_0 and 1_0) and the second search space includes the schedulingof all other control signaling (e.g., non-fallback DCI, all PDCCHconfigurations). In such an embodiment, because the SearchSpaceIds ofthe two search spaces are different, the gNB 120A explicitly indicatesthe second SSID to the UE 110 so that the UE 110 knows which searchspace to monitor for the non-fallback DCI and all PDCCH configurations.In some embodiments, the second search space is counted as one of thestandard-defined maximum of ten search spaces per cell. In someembodiments, the second search space is alternatively not counted as oneof the standard defined maximum of ten search spaces per cell.

At 415, the gNB 120A configures a beam failure recovery (BFR) searchspace. In some embodiments, the BFR search space (recoverySearchSpaceId)is only configured in the SpCell. In some embodiments, the BFR searchspace (recoverySearchSpaceId) is only configured in the SCell. In someembodiments, the gNB 120A may choose which cell to configure the BFRsearch space (recoverySearchSpaceId).

At 420, the gNB 120A configures whether downlink (DL) and/or uplink (UL)DCI transmissions are scheduled by the second search space of the SCell.In some embodiments, both the first search space of the SpCell and thesecond search space of the SCell schedule DL and UL DCI for UEoperations on the SpCell. In some embodiments, the gNB 120Aalternatively restricts which DCI (DL or UL) the UE 110 is configured tomonitor on the SCell.

At 425, the gNB 120A transmits an RRC configuration to the UE 110 thatincludes a first SearchSpaceId corresponding to the first search spaceand a second SearchSpaceId corresponding to the second search space sothat the UE 110 knows which search space(s) to monitor for controlsignals that schedules operations on the SpCell. In some embodiments,the RRC configuration further includes the BFR search space ID.

As currently defined by the Third Generation Partnership (3GPP)standards, the total number of different DCI sizes monitored by the UE110 is four. The total number of different DCI sizes for DCItransmissions scrambled by cell radio network temporary identifier(C-RNTI) monitored by the UE 110 is three. In some embodiments, the UE110 is limited to these maximums on both the first and second searchspaces. In some embodiments, the UE 110 is alternatively limited tothese maximums on each of the first and second search spaces. In such anembodiment, the UE 110 may report to the gNB 120A whether it supportsthe additional DCI size monitoring limitation associated with applyingthe size limit on a per cell basis.

FIG. 5 shows a method 500 of configuring a UE 110 to handle deactivationof an SCell configured to schedule transmissions on a SpCell accordingto various exemplary embodiments. The following description is made withthe assumption that the SpCell is a 5G cell and the SCell is a 5G cell.

At 505, the gNB 120A (or 120B) configures an SpCell (e.g., gNB 120A) andan SCell (e.g., eNB 122A) to schedule control data transmissions (e.g.,DCI) for the SpCell. At 510, the gNB 120A configures a first searchspace having a first SearchSpaceId in the SpCell and a second searchspace having a second SearchSpaceId in the SCell. At 515, the gNB 120Atransmits an RRC configuration to the UE 110 including theSearchSpaceIds of the first and second search spaces. At 520, the gNB120A provides an indication to the UE 110 regarding which search spaceto monitor (which search space is activated) when the SCell isdeactivated or dormant.

In some embodiments, the indication provided by the gNB 120A at 520 isan implicit indication. In such an embodiment, when the UE 110 receivesan indication that the SCell has been deactivated or is dormant, the UE110 implicitly knows that the second search space is deactivated and thefirst search space is activated. Similarly, when the UE 110 receives anindication that the SCell has been activated, the UE 110 implicitlyknows that the second search space is activated and the first searchspace is deactivated.

In some embodiments, the indication provided by the gNB 120A at 520 maybe an explicit indication. In such an embodiment, the gNB 120A maytransmit a DCI or a medium access control (MAC) control element (CE) toindicate to the UE 110 which search space the UE 110 should monitor. Insome embodiments, the gNB 120A may configure a timer to address ascenario in which the DCI/MAC CE is not received or improperly decodedby the UE 110. The timer begins when the DCI/MAC CE is received. Uponexpiration of the timer, the UE 110 begins to monitor a default searchspace. For example, if the DCI/MAC CE indicates that the UE 110 shouldmonitor the second search space, the UE 110 monitors the second searchspace until the expiration of the timer, at which point the UE 110monitors the first search space, which is configured to be the defaultsearch space. If the gNB 120A intends for the UE 110 to continue tomonitor the second search space, then the gNB 120A sends another DCI/MACCE indicating that the UE 110 should monitor the second search space.Upon receipt of the second DCI/MAC CE, the timer is reset. In someembodiments, the timer is set to 100 ms. It should be noted that thedefault search space may be configured to be either of the first orsecond search spaces.

In some embodiments, the configured SCell at 505 may be a plurality ofSCells. In such an embodiment, only one of the plurality of SCells isactivated at any given time for monitoring the control signaling thatschedules operations on the SpCell. In some embodiments, the activatedSCell may be indicated explicitly by the gNB 120A to the UE 110 when anSCell is deactivated or dormant via, for example, a DCI or MAC CE. Insome embodiments, the activated SCell may be determined based on apriority based on a plurality of predetermined factors such as, forexample, the periodicity of the search space in each SCell that isconfigured to schedule the control data signaling on the SpCell, theSearchSpaceId of each search space in each SCell that is configured toschedule the control data signaling on the SpCell, and the cell index(ServCellIndex) of each SCell. For example, a search space with a lesserperiodicity would have a higher priority than a search space with agreater periodicity.

Those skilled in the art will understand that the above-describedexemplary embodiments may be implemented in any suitable software orhardware configuration or combination thereof. An exemplary hardwareplatform for implementing the exemplary embodiments may include, forexample, an Intel x86 based platform with compatible operating system, aWindows OS, a Mac platform and MAC OS, a mobile device having anoperating system such as iOS, Android, etc. The exemplary embodiments ofthe above-described method may be embodied as a program containing linesof code stored on a non-transitory computer readable storage mediumthat, when compiled, may be executed on a processor or microprocessor.
